Hi guys. Doing LS 6.0 turbo setup in my 81' malibu,wondering which is best way to go on this. Some have said speed density with just map sensor is better and other with mass air sensor is better because o2 sensors are active but I'd think the mass air sensor in front of turbo intake would restrict air flow intake. Using OEM computer,high impedance injectors and sending harness off to be modified for what I need. Thanks
